Instructor: Allan Adams

In this lecture, Prof. Adams discusses a series of thought experiments involving "box apparatus" to illustrate the concepts of uncertainty and superposition, which are central to quantum mechanics. The first ten minutes are devoted to course information.

    I've been to 3 universities in the past 15 minutes: MIT, Harvard, and Stanford. You could say I'm something of a genius.

    This is an absolutely great professor. I wish I had professors like him.
  • This guy fucking loves what he knows, and he wants you to love it too, which is incredibly refreshing.
  • Took a quantum mechanics course from a desi guru who happens to be among the toppers and I gave up thinking I'm not good enough..this guy made me go over 6 lectures in a week and still hungry to go over again....inspiration is the key to make passionate innovators or scientists or teachers...I wish I had them...good luck to all of you lucky ones who gets to be inspired in early days..inspire your little ones too...

    wow.... we need more professors like him. Most physics and math professors laugh at questions. Like "what are you talking about. That's just a bad question. STFU and let me move on" instead of "what do you mean by that so I can correct your misunderstanding that like 8 other people in the class probably also have" which is clearly how this guy teaches. In other words, he actually teaches.

    32:56 "The miracle is not that electrons behave oddly. The miracle ist that when you take 10^27 electrons, they behave like cheese."
  • Heisenberg and Schrodinger are speeding down the highway when a state cop pulls them over. The cop walks up to the window and asks Heisenberg, "Do you know how fast you were going?" Heisenberg replies, "No, but I knew where I was." The cop says, "You were going over 90 miles per hour!" To which Heisenberg replies, "Fine. Now we're lost." Thinking this answer is a little strange, the cop decides to investigate the vehicle. He begins by opening the trunk. Shocked by what he finds, he shouts, "You have a dead cat in here!" Schrodinger answers, "Well I do now!"

    I was quite sucky at physics in high school, but I've always been really fascinated by QM, even though I never really got a full grasp of it. Now having found this video, I'm starting to get the basics and that honestly feels amazing! I've never seen such an enthusiastic and fun prof. as Prof. Adams & am really glad I have the opportunity to listen to him teach! :)

    Prof Adams passion is what kept the students and audience glued

    When he turns to the crowd and asks „Questions?“ Me: Yes, why am I here at 2am?
  • @mercster
    I'm almost as amazed at MIT's complex blackboard system than the quantum superposition of subatomic molecules.

    The most nourishing bit of information in this lecture is at the very end. Our intuition is formed from experience in the macroscopic world, which is totally different from the microscopic quantum world. This explains our frustration with counter intuitive results when trying to understand quantum experiments, since our intuition is not adapted to the quantum domain. Its like learning a new language. Thank you MIT for sharing.

    This is the type of professors we need to heal our academic traumas
  • @jasonchiang251
    he's so passionate about the topic. Really a great professor
  • @fabiorestrepo98
    I just learned Dr. Adams was born in my same city (Bogotá, Colombia). What a pleasant surprise, professor :)

    I'm a 40 year old man, passionate about the understanding of how the universe works and when he said "except you're all wrong" i've got emotional for a moment because it was a kind of illumination giving me an instantaneous sense of awareness to the existence.
